The image you uploaded is a multiplication table, commonly referred to as "Tables de Multiplications" in French. This table displays the results of multiplying numbers from 0 to 12 by each other. Below, I will explain how to use this table and solve problems using it.
---
Understanding the Table
1.
Rows and Columns:
- The table is organized into rows and columns.
- The first row and the first column contain the numbers from 0 to 12.
- Each cell in the table represents the product of the number in its corresponding row and column.
2.
Example:
- To find \( 7 \times 8 \):
- Locate the row for 7.
- Locate the column for 8.
- The intersection of row 7 and column 8 gives the result: \( 7 \times 8 = 56 \).
3.
Structure:
- The table is symmetric along the diagonal (from top-left to bottom-right), meaning \( a \times b = b \times a \). For example, \( 4 \times 9 = 9 \times 4 = 36 \).

How to Solve Problems Using the Table
Let’s solve a few examples to illustrate how to use this table effectively.
####
Example 1: Find \( 9 \times 6 \)
- Locate the row for 9.
- Locate the column for 6.
- The intersection of row 9 and column 6 gives the result: \( 9 \times 6 = 54 \).
####
Example 2: Find \( 12 \times 11 \)
- Locate the row for 12.
- Locate the column for 11.
- The intersection of row 12 and column 11 gives the result: \( 12 \times 11 = 132 \).
####
Example 3: Find \( 5 \times 7 \)
- Locate the row for 5.
- Locate the column for 7.
- The intersection of row 5 and column 7 gives the result: \( 5 \times 7 = 35 \).
####
Example 4: Find \( 0 \times 12 \)
- Locate the row for 0.
- Locate the column for 12.
- The intersection of row 0 and column 12 gives the result: \( 0 \times 12 = 0 \).
####
Example 5: Find \( 11 \times 3 \)
- Locate the row for 11.
- Locate the column for 3.
- The intersection of row 11 and column 3 gives the result: \( 11 \times 3 = 33 \).

General Tips
1.
Zero Rule: Any number multiplied by 0 is 0. For example, \( 0 \times 12 = 0 \).
2.
One Rule: Any number multiplied by 1 is the number itself. For example, \( 1 \times 9 = 9 \).
3.
Symmetry: Since multiplication is commutative (\( a \times b = b \times a \)), you can switch the order of the numbers if it helps. For example, \( 8 \times 7 = 7 \times 8 = 56 \).

Final Answer
The multiplication table provides a quick reference for finding the product of any two numbers between 0 and 12. By locating the appropriate row and column, you can easily determine the result.
